The Grand Canyon is a colorful steep-sided gorge carved by the Colorado River in the U.S. state of Arizona. It is largely contained within the Grand Canyon National Park — one of the first national parks in the United States.
The canyon, created by the Colorado River over a period of 6 million years, is 277 miles long, ranges in width from 4 to 18 miles and is more than a mile in depth.
During prehistory, the area was inhabited by Native Americans who built settlements within the canyon and its many caves. The Pueblo people considered the Grand Canyon a holy site and made pilgrimages to it.
The first European known to have viewed the Grand Canyon was García López de from Spain, who arrived in 1540.
The Grand Canyon was largely unexplored until after the U.S. Civil War. In 1869, Major John Wesley Powell, a one-armed Civil War veteran with a thirst for science and adventure, made the first recorded journey through the canyon on the Colorado River. He accomplished this trek with nine men in four small wooden boats, though only six men completed the journey. Powell referred to the sedimentary rock units exposed in the canyon as "leaves in a great story book".
The Grand Canyon is unmatched throughout the world for the vistas it offers to visitors on the rim. It is not the deepest canyon in the world. The Cotahuasi Canyon (11598 feet) and Colca Canyon (10499 feet), both in Peru are deeper. The Grand Canyon is known for its overwhelming size and its colorful landscape.

We live on the Earth. Our Earth is a part of a Solar System. Our solar system consists of the Sun, planets, moons and other celestial bodies. All planets including Earth, revolves around the Sun. There are eight planets in the solar system. In order of their distances from the Sun, the planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Natural satellites, usually termed as moons after Earth's Moon, orbit around the planets. There are 166 known moons for all eight planets. Our moon is the only moon that we can see from the Earth without the help of any telescope. Other then planets and moons, there are other smaller objects such as asteroids, Kuiper belt objects, comets, meteoroids, and interplanetary dust in the solar system.
Mercury, Venus, Earth, Mars are termed as inner or terrestrial planets. They have dense, rocky compositions, few or no moons, and no ring systems. The four planets Jupiter, Saturn, Uranus, and Neptune are termed as outer planets or gas giants. These outer planets collectively make up 99 percent of the mass known to orbit the Sun. Jupiter and Saturn's atmospheres are largely hydrogen and helium. Uranus and Neptune's atmospheres have water, ammonia and methane. |
